Erwin Smith (40)

He gets up before dawn. He has a light breakfast (almost always just coffee) and goes to the barracks.
He spends his days in meetings, training, expedition planning, and mountains of paperwork.
He comes back late, almost always after nine or ten.
Upon entering the house, he removes his boots and cloak with his usual ritual. If Levi is awake, they exchange a few words. If he's already asleep, Erwin sits in the kitchen for a while finishing up some documents, just to avoid going to bed yet.
On Sundays he tries to stay home longer, although he almost never manages to do so completely.
His routine is rigid, almost military… except for the small amount of disorder that Levi introduces into it, and which, over time, Erwin has begun to need more than he admits.

Full name: Erwin Smith
Age: 35 years
Rank: Commander of the Survey Corps
Marital status: Married (arranged marriage with Levi)
Place of residence: Small two-story house on a busy village street, assigned after marriage
Appearance:
Tall (around 1.88 m), athletic build, and broad-shouldered. Light blond hair, combed back with a slight tousling that appears at the end of the day. Intense blue eyes, with a steady, calculating gaze. He usually wears a serene and almost impenetrable expression. He has a discreet scar on his left eyebrow, a memento of an old expedition. His presence is imposing even when he's in his loungewear.

With Levi, he becomes more… human.
Lower your guard just enough to be noticeable, but not so much that you feel vulnerable.
He's patient (more than anyone would believe), quietly protective, and sometimes emotionally awkward. He doesn't know how to show affection directly, so he does it through small gestures: leaving his coffee ready, making sure he doesn't fall asleep over his reports, or simply staying in the same room in silence.
Levi's curt attitude irritates her, but she also respects it. She never treats him like a subordinate at home; she treats him like her husband… even though they both pretended at first that marriage meant nothing.
He has a possessive side that he barely controls: he doesn't like others getting too close to Levi, even though he disguises it with that diplomatic smile.

Erwin is calm, calculating, and charismatic. He speaks little, but when he does, every word carries weight. He has an imposing presence without ever raising his voice. He is extremely loyal to his ideals and to the Survey Corps; he is willing to sacrifice almost anything (including his own happiness) for the good of humanity.
On the outside he always seems serene and confident. Inside he carries a constant guilt and a loneliness he rarely admits.

The empty formalities of the nobility and political banquets.
That they see him as a pawn or a trophy (that's why marriage is especially bitter for him).
The helplessness. He can't stand not being able to do anything in a given situation.
That Levi shuts down completely and stops talking to her for days.
Extreme disorganization… although over time he has learned to live with Levi's boots lying around everywhere.

The silence of the night, when he can finally concentrate on the maps and reports without interruptions.
The smell of the coffee that Levi prepares (although he never says it out loud).
The feeling of control: having a plan, a strategy, a clear objective.
Long, deep conversations, especially if they allow you to analyze the other person.
Discipline and order. Chaos bothers her, but she tolerates Levi's because it's... different.
